REVERSIBLE PLOW',

Application led November 13, 1924. Serial No. 749,755.

To all whomy t may concern.'

Be it kno-wn that l, HENRY J. NnUrANe, a citizen of the United States, residing at Atlanta, in the county oi' Steuben and State ot New York, have invented certain new and useful Improvements in Reversible Flows, ot which the ollowing is a specilication. A

My invention relates to an improvement in reversible plows.

Tt has for its primary objectacility in turning the plows over at the end of the Ylfurrow, in order to make it possible to plow back along the same furrow, without plowing around the land as is necessary with the old-fashioned mold-board plow;

rThere are two main features in this present invention, one ot which includes simple means for reversing the plows from the front ofthe machine, and the second is the means for turning and adjusting the caster- \vheel located at the rear, also from the front of the machine, so that both means for .the adjustment of the machine are easily reached and manipulated from a` common point at the 'front oit the machine.

Tn the acc-on'ipanying drawings Fig. 1 is aside elevation of my improved plows;

is a fragmentary view in longitudinal section;

Fig. 3 is a similar plan view;

Fig. i is a. section on line 11 of Fig. 3 loo-king in the direction of the arrow;

Fig. 5 is a view of the Wishbone bracket on the end of the adjustable sleeve which carries the plows and colters or jointers; and

Fig. 6 is a bottom plan View ofthe pivoted segment lon the caster-wheel spindle.

The numeral 1 represents a tubular bar constituting the central framework of the machine. This is supported at the forward end on wheels 2 made vertically adjustable by the hand-lever 3, and the caster-wheel 4 at the rear.

A sleeve 5 is mounted and capable of being turned or axially adjusted upon theycentral tubular bar 1.

The plows 6 and the colters or jointers 7` are secured to this sleeve in any approved manner, as, for instance, by the tastening means S. A wish-bone bracket 9 is secured by bolts 10 to the Jforward end of the sleeve 5. A trip-bar 11 is rotatably supported in bearings 12 located on theframe of the ma.-

toothed segment 13 is keyed upon the forward end ot the tripping bars 11, and the teeth et this segment mesh with the teeth ot the pinion 111 on the shaft 15. Shaft 15 kturns in bearings 16 on the 'frame of the 1nachine, and has a crank 17 at the forward end 'thereof which the operator manipulates when he desires to reverse the plo-ws. Means .is provided for locking the sleeve 5, which carries the plows and colters, in its extreme position. This is provided for by means of a slide-bolt 18 actuated in one direction by a spring 19, and holes 2O vare provided in the collar 21 on the sleeve at opposite points to receive this bolt 18 as shown in Fig. 2. Stop-shouldeis 22, one on either side, limit the movement of the sleeve in each direction. The spring-actuated slide-bolt 18 is operated by the hand-lever .13 through the rods 21`and 25 and lever 26 as a simple means for pulling the bolt out of engagement with the hole 2O in the collar 21.

Tt is sometimes desirable to adjust the position of the caster-wheel at the rear of the machine, and especially on hilly soil to counteract the tendency of the plow to work' downwardly away from'the land in plowing. This adjustment is accomplished through the medium of a shaft 27 extending through the tubular bar 1, as viewed in Figs. 2 and 1. This has a bevel pinion 28 on the rear end which engages the teeth of the fanshaped segment 29, which segment is held on the spindle 30 of the caster-wheel by a set-screw orother means 31, as viewed in Figs. 1, 2, 3 and 6.

VOn the orward'end of the machine, the crank 32 is provided as a convenient means tor turning the shaft 27. A toothed wheel 33 is secured on-the shaft 'adjacent to the crank, and a pivoted lat-ch 34 is employed as a means for locking it in its adjusted position. Thus all means yof adjustment are brought kto a common point within easy reach of the operator, making it easy toy shift or reverse the plows and adjust the casterwheel.

l claim:

l. In a reversible plow the combination of a tubular bar, a sleeve rotatably mounted thereon, and a sha'lt rotatable within the tubular bar, plows carried by the sleeve, a caster-wheel for the support ot the rear end of the tubular bar, and separate and independent means located at the it'orward end of the plow tor reversingl the plows and for steering` the caster-wheel 'through the medium of the sha'tt.

2. In a plow the combination ot a tubular bar, earth working means carried thereby, adjustable wheels ior the support ot the 'forward end ot said bar, and a caster wheel supporting the rear end, a shaft eX- tending through the tubular bar and having` a crank on one end, by which it is turned, and means at the other end for transmitting motion to the spindle ot the caster-wheel for steering the latter.

3. ln a plow the combination oi a tubular bar, earth working means carried thereby, adjustable wheels tor the support oit the forward end ot' said bar, and a caster wheell supportingl the rear end, a shall't` extending through the tubular bar and having a crank on one end, b v which it turned, means at the other end for transmitting,- motion to the spindle ot the caster-wheel ilor steering the latter, and means 'lor locking;v the sha'lt.

y4t. ln a plow the combination of a tubular bar, earth working means carried thereby, a shaft extendingthrough said tubular bar and rotatable therein, and having a bevel pinion at the rear end and means t'or turn ingl said ,sha-ft at the forward end, a casterwheel having a spindle which has a toothed segment engaged by the pinion, and means connected with Jhe shaft and the tubular bar for locking the latter.

In a reversible plow the combination of a bar, wheels for supporting` the latter, a sleeve rotatably mounted upon the bar, and

adapted to carry two sets of plows thereon,

a Wishbone bracket secured to the torwardv end of said sleeve, a rotatably supported trip-bar having an end extending into the Wishbone bracket as a means for shifting the bracket and reversing the plows, means for turning the trip-bar, means for limiting the rotation of the sleeve, and means for locking` the sleeve.

6. In a reversible plow the combination of a bar, wheels for supporting,l the latter, a sleeve rotatably mounted on the bar, earth working means carried'by said sleeve, a Wishbone bracket secured to the sleeve, a rotatable trip-bar, one end ot which extends into the wishbone bracket, a pinion on the opposite end, a toothed segment keyed on the bar, a shaft having` a pinion engaging the teeth of the segment, a spring-actuated slidebolt for locking the sleeve, and means for limiting the movements of the sleeve.

7. In a reversible plow the combination of a tubular bar, wheels for supporting the latter, a sleeve rotatably mounted on the bar, plows carried by said sleeve, a wishbene bracket secured to the sleeve, a rotatable trip-bar, one end ot' which extends into the Wishbone bracket, a pinion on the opposite end, a toothed segment keyed on the bar, a shaft havingl a pinion engaging the teeth of the segment, a spring-actuatedV slidebolt 'for locking the sleeve, means for limiting the movements ol the sleeve, a shaftt rotatably supported within the tubular barA and having a crank on one end for operating the same, and 'a beveled pinion on the opposite end, toothed segments secured to the spindle of the rear wheel, the teeth of which are engaged by the beveled pinion, and means for locking` said shaft in any position to which it is turned.

In testimony whereof I affix my signature.

HENRY J. NEUFANG.
